Parenting floor fail

Hi, Why do I fall through parented floors?

I’'m making a moving house sorta thing, and I’ve parented a lot of details into it including the floors, and I keep falling through them. Is there any way to avoid falling through as I step on them?

What do you mean? Your useing a parrent tool and you keep gliching thru the floor? If you were trying to put props into the ground, use the avd ball-socket tool on default settings and then click on the prop and the ground.
